Power and bandwidth efficiency of wireless mesh networks

Abstract

As a prevalent network topology, mesh, has been actively researched and developed as a key solution to improve the performance and services of wireless communications. In this study, the authors carry out a comprehensive analysis of the bandwidth efficiency (BE) in b/s/Hz and power efficiency (PE) in b/s/Hz/W of carrier sense multiple access with collision avoidance, the basic medium access control protocol for wireless mesh networks (WMNs). Analysis results show that the suboptimal, not the maximal, power and BE can be achieved simultaneously under the same conditions, for example, the number of competing nodes and contention windows. Hence, the authors present a heuristic bandwidth-PE tradeoff design. Simulation results show that the authors proposed protocol works well in both single-hop and multi-hop WMNs.

Energy aware cross layer-based connection admission control mechanism for wireless mesh networks

“…Cao et al (2008) proposed a mechanism for (WMC) capable of maintaining the stream of data packets. An efficient CSMA/CA scheme is proposed by Zhao et al (2013) for efficiency in both power and bandwidth. Ding et al (2013) defined a solution optimised for on-demand video applications in the networks having high capacity The current model advocated a fusion of multi-path routing and allocation of spectrum to reduce the total cost of bandwidth in the network.…”
